The Olympics and Paralympics ticket resale website remained out of action today due to technical issues and London 2012 organisers said they didn't know when it would be up and running again.
In another ticketing embarrassment for organisers, the system was suspended only a few hours after being launched on Friday morning and has remained problematic ever since.
A spokesman for the London 2012 Organising Committee (Logoc) said today: "Our focus is on resolving the issues on the website and getting [ticket agents]Ticketmaster to get it back up and running again."
In an earlier statement, Logoc said :"We have told Ticketmaster to suspend the resale system whilst they investigate some issues customers have been experiencing.
"We want buying and selling Olympic and Paralympic tickets through Ticketmaster to be a good customer experience so we will re-open the site once Ticketmaster have resolved these issues."
People trying to buy tickets were able to click on to apparently available tickets, but after several minutes were told these were not available.
However, hours later, the website showed the same tickets still apparently available.
The Logoc spokesman said this was due to tens of thousands of people trying to buy the tickets and a delay in those tickets being removed from the system once they had been purchased.
The resale window is open until February 3, and a further one million "contingency" tickets are due to go on sale in May.
Around 1.2 million people, or two thirds of applicants, ended up empty-handed after the first round of ticket sales and the second round also experienced major issues.
Organisers have insisted their balloting system has been the fairest way to allocate tickets with such heavy demand.
